I had a go at entering all the settings but registration failed. On the vyke site you can download a configurator which sets up your voip settings for you. Seems to do the same job as entering them manually as you don't even need another app, it uses the built in internet telephony. If you want to enter all the settings manually for Vyke though, here they are (taken from the profile configured by Vyke):Profile name: VykeService profile: IETFDefault access point: <your choice>Public user name: sip:<Vyke user id>@sip.vyke.comUse compression: NoRegistration: When neededUse security: No
